Nvidia's ACE technology enables lifelike conversations with AI game characters.

Nvidia showcased a demo at Computex 2023 in Taipei, featuring a cyberpunk ramen shop where players can talk to the proprietor using their own voice. The demo was built using Nvidia's ACE middleware, which includes NeMo tools for deploying large language models and Riva speech-to-text and text-to-speech. While the generative AI reacts to natural speech, the dialogue leaves much to be desired. The ACE toolkit can scale to more than one character at a time and could theoretically even let NPCs talk to each other.
